Monitoring device for a vacuum toilet
First Claim
1. A monitoring device for monitoring a vacuum toilet, comprising:
- a position detector adapted to detect a position of a toilet lid;
a mechanical latching device that latches the toilet lid in an open position, the mechanical latching device including a first latching element and a second latching element; and
a flushing control unit adapted to control a flushing operation of the vacuum toilet based on a detection of the position of the toilet lid,wherein the mechanical latching device latches the toilet lid in response to a weight of a person acting on a toilet seat such that a movement of the toilet lid from the open position to a closed position is blocked by an overlap between the first latching element and the second latching element, andwherein the flushing operation is blocked upon the detection of the toilet lid in the open position.

Abstract
A monitoring device and method are provided for monitoring a vacuum toilet, as well as a personal transport vehicle, in particular an aircraft, which uses a monitoring device for vacuum toilets. The monitoring device has a position detector for detecting the position of a toilet lid, a mechanical latching device and a flushing control unit. The latching device is designed to latch the toilet lid in an open position based on the weight of a person acting on a toilet seat. The flushing control unit is further designed to control the flushing operation based on the toilet lid position, and to block the flushing operation upon detection of the toilet lid in the open position. This makes it possible to improve both the comfort and hygienic conditions for the toilet user while using the vacuum toilet.

15. A method for monitoring a vacuum toilet, the method comprising the steps of:
-
mechanically latching a toilet lid in an open position with a mechanical latching device including a first latching element and a second latching element to block a movement of the toilet lid from the open position to a closed position by a weight of a person acting on a toilet seat that causes an overlap between the first latching element and the second latching element; detecting a position of the toilet lid using a position detector; controlling a flushing operation based on the detecting the position of the toilet lid by the position detector; and blocking the flushing operation given the detecting of the toilet lid in the open position. - View Dependent Claims (16, 17, 18, 19)

20. A transport vehicle, comprising:
-
a vacuum toilet; a monitoring device adapted to monitor the vacuum toilet, the monitoring device comprising; a position detector adapted to detecting a position of a toilet lid; a mechanical latching device that latches the toilet lid in an open position, the mechanical latching device including a first latching element and a second latching element; and a flushing control unit adapted to control a flushing operation of the vacuum toilet based on a detection of the position of the toilet lid, wherein the mechanical latching device latches the toilet lid in response to a weight of a person acting on a toilet seat such that movement of the toilet lid from the open position to a closed position is blocked by an overlap between the first latching element and the second latching element, and wherein the flushing operation is blocked upon the detection of the toilet lid in the open position.
